| Some curious results produced by ex-

The dynamic value of one pound of good
steam coal has been estimated by Prof. w.
d. Rogers as equivalent to the work of one
man one day, while three tons would repre-

estimated that four-foot seam would yield
one ton of good coal to the square yard,
and that one square mile in area would
represent the labor Of over 100000 mon

The march of progress is shown by the
following statement: 1T is now possible to
construct complete sewing machine in a
minute or sixty in one hour; a reaper every
fifteen minutes or less; 300 watches ina day,
complete in all their appointments. More
important than this even is the fact that it
is possible to construct a locomotive In a
day From the plans of draughtsman to
the execution OF them by the workmen every
wheel, lever, valve and rod may be con-
structed from the metal TO the engine in
tact Every rivet may DO driven in the
boiler, every tube in the tube sheets, and
from the smokestack 70 the ash pan loco
motive may be turned out in a working day,
completely equipped, ready to do the work
